QRCoder is a .NET library, completely written in C#, which enables you to generate QR Codes as defined by ISO/IEC 18004. The main target of the QRCoder library is to deliver a small and easy-to-use solution, which has no dependencies to other libraries or network stacks. (Like QR Code generators which are relying on online services which makes them vulnerable/slow in some cases.) Although simplicity is one of the main goals, QRCoder is really flexible, in both "output formats" as well as in "payload types". Payload types? Yes, QRCoder brings its own "payload generator", which helps you to create a big list of different payload types to generate special QR codes like "WiFi QR Codes", "Girocodes", "SwissQRCodes" and many more.

EFQRCode is a lightweight, pure-Swift library for generating stylized QRCode images with watermark or icon, and for recognizing QRCode from images, inspired by qrcode. Based on CoreGraphics, CoreImage, and ImageIO, EFQRCode provides you a better way to handle QRCode in your app, no matter if it is on iOS, macOS, watchOS, and/or tvOS. You can integrate EFQRCode through CocoaPods, Carthage, and/or Swift Package Manager.
